When booting up the Unreal Editor for version 4.15 and when loading a project in 4.15 I get an error popup with a Quit and Ok option stating Unreal “Failed to create Session”. Pressing OK dismisses the error and Unreal launches properly. Is there some way to fix this? Do I need to disable something?
Thank you
i have the same problem
Hi VFSdswieczko,
Does your project have a Create Session node or are you trying to create a session in C++ in this particular project? Is there a plugin active that is trying to create a session?
As a troubleshooting step, open a blank Third Person Blueprint template and set the map to be the default startup map for UE4.15 in your Project Settings>Default Maps (Disable this in your original project.) Do you still get this error when opening the default project?
Hi , thanks for the response. We got new computers and a fresh install of Unreal and I no longer get the error so I can’t check your solution. Hopefully your response helps other people having the same problem. I didn’t have any create session nodes that I was aware of and was using single player projects that worked without issue on 4.12.
I got this error with stock 4.15.1 launching the editor with no project or with a basic project.
It seemed to be coming from having the Oculus VR Runtime Service running with no Oculus device attached. Hitting “OK” and skipping past it the error dialog seemed to work ok. Stopping that service (under Windows services) before starting the editor seem to fix it . Also disabling VR plugins (including SteamVR) in the editor in the Plugins settings UI and restarting the editor seems to prevent it from happening further.
That works for me.
Just close the Oculus VR Runtime Service.
Thanks very much!
